Answer:
y = -2x + 4
Step-by-step explanation:
The line intercepts at the y axis at 4. And you go to units down then one unit right to get to the next point.
You have to isolate the (a) so you multiply the 2/3 by 3/2 and you have to do that to the right side. So -24 times 3/2 equals to -36. Therefore, a=-36.
Answer: x^3 - a^3 = (x - a) (x^2 + ax + a^2) is an identity
Step-by-step explanation:
Verify the identity using trig rules.
In both cases, we can use a rule of three.
<h2>First part</h2>

Therefore, 4 students correspond to 20% of 20 students in total.
<h2>Second part</h2>

Therefore, 2 doctors correspond to 8% of 25 doctors in total.
